Advice needed on which portable oscilloscope is best

[Stephen Brett Davey]

I am looking at buying my first Portable Digital Oscilloscope.

It will need to have...
At least 2 isolated inputs.
Ch1 x Ch2 function to calculate Watts.
Bandwidth of 100MHz.
Record function.
8 or 12 bit vertical resolution.
FFT function.

I have looked at (but not used) the following...

Fluke 196C (2 inputs)

AEMC OX7104-C (4 inputs)

If anyone has used these or other similar oscilloscopes I would be
interested in hearing any good/bad comments you may have about them and
their use.

I have and am pretty happy with a 199C. Couple of comments:

The stock scope probes are fine but rather clunky. The tips require a
pretty good pull to remove them (straight pull, no twist or a "depress
this" button); they won't come off accidentally but you might think
you're having to pull *too* hard the first time you swap tips.

Reasonable battery life.

The FFT presentation is a bar graph (vertical line up to the data point)
rather than the more commonly seen line graph, with a line connecting
successive points. The bar graph is more correct (the FFT doesn't "know"
what's between the points) but a little harder to see.

Good selection of measurement options and trigger options.

The Flukeview software works well with the scope and the optically
isolated USB cable.

Got mine at http://www.tequipment.net/. Have purchased a few things from
them over the years and generally found them to have good prices. No
complaints. (#disclaimer: just a satisfied customer, etc.)
